The Lead: Tesla hits best prices in five months amid Model X optimism

Tesla Motors roared to its highest stock prices since March on Wednesday, as two investment banks predicted the SUV-style Model X could push the electric car maker's shares higher than $300.

Tesla shares jumped 4.4 percent to $248.93 Wednesday, its best one-day performance in nearly two months and within shouting distance of its record intraday high of $265. Morgan Stanley and Pacific Crest analysts released separate notes Wednesday that predicted that price will increase substantially in the future thanks to the coming launch of the Model X.

"Some in the market have described Tesla as a 'one hit wonder' with the Model S. We expect the Model X will put that to rest very, very quickly, Morgan Stanley analyst Adam Jonas wrote, later adding, "We'd be disappointed if the Model X did not sweep every major Car of the Year award by the automotive media."

Pac Crest analyst Brad Erickson chimed in with his own rosy view of Tesla's future, initiating coverage of Tesla with a $316 price target and writing, "we believe optimism around the launch of the Model X is likely to continue to rise."
